Where are my old downloads gone?

[finknottle]

I went away from my iBook (OSX.3.4 800 MHZ), using Limewire 4.0.6 Pro for a few minutes and when I came back it had frozen . This has happened twice before with 4.0.5 and with 4.0.6. Since these crashes I had done a clean install of OSX and reinstalled Limewire again (without the files waiting to be downloaded, new prefs etc. ). Over the past week I have been downloading away and had a lot of new files waiting to be downloaded, when the crash happened again as I said. This is different however in that after force quitting Limewire and restarting it, my files waiting to be downladed are gone!! There is nothing in the Downloads pane. Where are they gone?
Also why is Limewire so slow in downloading these days? I checked with my ISP in case they had brought in protocols to slow down P2P sharing but they have not. Esp. since the 'upgrade' to 4 it is worse. I have tried two other clients in the last few days and they give me much faster downloads. I am reluctant to switch however since I have a Limewire T Shirt I have been using Limewire for two years and am really dissappointed with this latest incarnation of it and it does not seem to be worth paying for anymore.
